Hi. I have a problem to extend my current volume group "vg01". I did: # pvcreate /dev/hde1 /dev/hde2 pvcreate -- physical volume "/dev/hde1" successfully created pvcreate -- physical volume "/dev/hde2" successfully created # vgextend -v vg01 /dev/hde1 vgextend -- locking logical volume manager vgextend -- checking volume group name "vg01" vgextend -- checking volume group "vg01" existence vgextend -- checking for inactivity of volume group vgextend -- reading data of volume group "vg01" from lvmtab vgextend -- INFO: maximum logical volume size is 255.99 Gigabyte vgextend -- reading data for all physical volumes from disk(s) vgextend -- extending VGDA structures of volume group "vg01" vgextend -- volume group "vg01" will be extended by 1 new physical volumes vgextend -- extending volume group "vg01" by physical volume "/dev/hde1" in kernel Segmentation fault (core dumped) I am using RedHat 7.1 with a custom kernel to have LVM (2.4.9-6). I have 2 drives on this IDE controller (a Promise UltraDMA100DX2) and both work fine with linux. My secondary drive (/dev/hdf is already part of vg01). I don't know if this is a bug or if I am not using this correctly. I could not find anything on the internet about this particular problem. For more information, I am including the results of several commands. Let me know if you need more information. Thanks in advance for your help.
